WINDOW-SCREEN.

SPECIFIGATION forming part of'Letters Patent No. 768,416, dated August23, 1904.-

Application filed December 15, 1903. Serial No. 185,323. 1110 model.) v

To all whom, it may concern:

Be it known that 1, CHARLES Gr. VVOODS, a citizen of the United States,residing at'St. Louis, State of Missouri, have invented certain new anduseful Improvements in WindoW-Screens, of which the following'is aspecification, containing afull, clear, and exact demounted upon thewindow-casing; a screenw1nd1n g roller mounted in said bearing-plates; 1

a cord-winding pulley fixed upon said roller; stationary binding-stripsattached to the window-casing, the upper ends of said'strips beingrounded to act as edge-guides and one of said strips being grooved toreceive a spring and cord and there being retaining-notches at the lowerends of said strips; acord-guide roller at the upper end of said groove;a retractile spring attached at the lower end of said groove; a cordattached to said windingpulley, passing over the guide-roller andattached to said spring; ascreen-guide roller mounted in saidbearing-plates; a windowscreen attached to and wound upon said winding-roller, passing over said screen-guide roller, passing over saidedge-guides and down along said stationary binding-strips; a'movablebinding-strip attached to the lower edge of said screen and adapted toengage in said retaining notches; handles attached to said movablebinding-strip; clamping-levers attached to the window-casing, andedge-clamping strips carried by said clamping-levers to engage the edgesof said screen and press them firmly against said stationarybindingstrips.

In the drawings, Figure-1 is avertical section of a window with myimproved screen in position for use as seen looking in the direction ofthe arrow in'Fig. 2. Fig, 2 is an inside elevationas seen looking in thedirection indicated bythe arrow in Fig; 1, parts being broken away toeconomize space. Fig.

3 is a perspective detail, upon an enlarged scale, at one ofthe uppercorners of the window, parts being broken away. Fig. et is a perspectivedetail, upon an enlarged scale, of the lower part of thegroovedstationary binding-strip, the upper part being broken away. Fig. 5 is across-section, upon an enlarged scale, of the cord-winding pulley.

Referring to the drawings in detail, the

bearing-plates 6 are secured to the side pieces 7 of the Window-casingat the extreme upper ends and just inside of the parting-strips 8. Thescreen-winding roller 9 has its ends journaled in these bearing-plates,and the cordwinding pulley 10 has a square opening 11, through which thesquared end of the roller is inserted. The stationary binding-strips 12extend from top to bottom of the windowcasing, the upper ends 13 of saidstrips being rounded to form guides for the edges of the screen, and oneof said strips has a groove 14, and both of said strips haveretaining-notches 15 at their lower ends. The cord-guide roller 16. ismounted at the upper end of the groove 1 1 in line with the pulley 1O.The retractile coil-spring 17 is placed in the groove 14 and attached tothe lowerend of the strip 12. The

cord 18 is attached to the winding-pulley 10,

wound upon said pulley and attached to the spring 17. The screen-guideroller 19 is journaled in the bearing-plates 6 close to the lower faceof the upper casing-piece 20. The window-screen 21 is attached to thewinding-roller 9, wound upon said roller, passing over the guide-roller"19 and passing over the screenedge guides 13,and passing down along thestationary binding-strip 12. The movable binding-strip 22 is attached tothe lower edge of the screen 21 and is adapted to engage in theretaining-notches 15, and handles 23 are fastened to this movable strip.The clamping-levers 24 are pivoted to the plates 25, fastened to theinner faces of the casing-pieces 7. The edge-clamping strips 26 arecarried by the inner ends of the levers 24, the outer ends of saidlevers serving as-operatinghan dles, and said strips being in positionto press the edges of the screen againstthe stationary binding-strips.

In operation the handles 23 are manually engaged to pull the screendown, thereby unwinding the screen from the roller 9 and overcoming thetension of the spring 17 and winding the cord 18 upon the pulley 10.-Then the ends of the strip 22 are placed in the retaming-notches 15 andthe levers 2 L are op- .erated to press the clamping-strips 26 against.the edges of the screen and in turn press the edges against thebinding-strips 12. It is obvious that when the screen has been closed noflies or insects can pass through the window. Theguide-roller 19 holdsthe screen against the lower face of the casing-piece 20, the strip 22engages the upper face of the lower casingpiece 27 and the screenpressing against the strips 12, thus leaving no place for insects topass through.

I claim 1. In a window screen, bearing plates mounted upon thewindow-casing; a screenwinding roller mounted in said bearing-plates; acord-winding pulley fixed upon said roller; stationary binding-stripsattached to the window-casing, the upper ends of said strips beingrounded to act as edge-guides, and one of said strips being grooved toreceive a spring and cord, and there being retaining-notches at thelower ends of said strips; a cord-guide roller at the upper end ofsaidgroove; a re traetile spring attached at the lower end of saidgroove; a cord attached to said windingpulley, wound upon the pulley,passing over the guide-roller and attached to said spring; ascreen-guide roller mounted in said bearingplates; a window screenattached to and wound upon said Winding-roller, passing over saidscreen-guide roller, passing over said edge-guides, and down along saidstationary binding-strips; a movable binding-strip attached to the loweredge of said screen and adapted to engage in said i'etaining-nott'hes;handles attached to said movable bindingstrips; clamping-levers attachedto the windew-casing; and edge-clamping strips carried by saidclamping-levers to engage the edges of said screen and press them firmlyagainst said stationary binding-strips, substantially as specified.

2. In a window-screen, a screen-winding roller suitably mounted;stationary bindingstrips attached to the window-casing, the upper endsof said strips being rounded to act as edge-guides for the screen andthere being retaining-notches at the lower ends ofsaid strips; ascreen-guide roller mounted in position near the limits of thewindow-casing opening, a window-screen attached to and wound upon thesaid windingroller, passing over said screen-guide roller, passing oversaid edge-guides and down along said stationary binding-strips, amovable binding-strip attached to the lower edge of said screen andadapted to engage in said retaining-notches; clamping-levers attached tothe window-casing in apposition to the stationary bindingstrips andedge-elam 'iing strips carried by said clamping-levers to engage theedges of said screen and press them firmly against said stationarybinding strips, substantially as specified.

In testimony whereof I have signed my name to this specification inpresence of two subscribing witnesses.
